Does L-Carnitine Lower Cholesterol?

Many people are looking for natural ways to improve their cholesterol levels and overall heart health. One supplement that has gained popularity in recent years is L-Carnitine. But does L-Carnitine actually lower cholesterol? Let's dive into the research to find out.

What is L-Carnitine?

L-Carnitine is a naturally occurring amino acid derivative that plays a crucial role in the transportation of fatty acids into the mitochondria, where they are used for energy production. It is found in high concentrations in red meat and dairy products, but can also be taken as a supplement.

Research on L-Carnitine and Cholesterol

Several studies have looked at the effects of L-Carnitine on cholesterol levels. A meta-analysis published in the journal Metabolism found that L-Carnitine supplementation was associated with a significant decrease in total cholesterol levels. Another study published in the American Journal of Clinical Nutrition reported that L-Carnitine supplementation led to a decrease in LDL cholesterol, often referred to as "bad" cholesterol.

How Does L-Carnitine Lower Cholesterol?

The exact mechanism by which L-Carnitine lowers cholesterol is not fully understood. However, it is believed that L-Carnitine may help to increase the breakdown of fats in the body, leading to a decrease in cholesterol levels. Additionally, L-Carnitine has been shown to have antioxidant properties, which may also play a role in its cholesterol-lowering effects.


While more research is needed to fully understand the effects of L-Carnitine on cholesterol levels, the existing studies suggest that L-Carnitine may indeed have a positive impact on cholesterol levels. If you are considering adding L-Carnitine to your supplement regimen, be sure to consult with your healthcare provider to determine the best approach for your individual needs.
